Product Description:

The MKD090B-085-GG1-AN is a servo motor produced by Bosch Rexroth Indramat and included in the MKD Synchronous Motors series. It is intended for closed-loop motion axes in packaging machines, material-handling cells, and other industrial automation stations where precise torque generation and position reporting are required. The motor interfaces with a compatible drive controller to translate current into shaft rotation so that mechanical loads can follow programmed velocity or position profiles.

The motor supplies a continuous standstill torque of 12.0 Nm, allowing the drive to hold or slowly move loads without additional gearing. Its housing carries an IP65 protection rating, which keeps internal windings, bearings, and feedback devices sealed against dust ingress and water jets during normal washdown procedures. A square mounting flange measuring 140 mm simplifies installation with other IEC-sized machines of similar power. Rotor position is returned through resolver feedback (RSF); this analog device withstands high temperatures and electromagnetic noise while still providing fine incremental data to the controller. The electrical-to-mechanical alignment accuracy is ±8 angular minutes, which supports repeatable positioning tasks such as indexing or cut-to-length operations.

The integrated holding brake applies 11 Nm of static torque to secure vertical or suspended loads whenever the drive is disabled. For coaxial alignment with gearboxes, the front face provides a centering diameter of 110 mm. The motor uses a plain shaft with a shaft seal, which helps prevent lubricant leakage and maintains protection against spray. Power and feedback cables exit on Side A through an output connector, keeping wiring on the same side of multiple motors in a machine frame. Thermal class F insulation, motor size 090, and length code B are matched to the motor package for operation within an ambient range of 0–40 °C. Relative position detection, together with resolver data, lets the drive recover alignment after short power interruptions without requiring an absolute encoder.
